I agree with you that no getting into directory index, at least this time.
Howerver, I don't agree (or disagree) with your on memory indexing idea yet.

nilfs has there own btree functionality, therefore it is goot to be used for 
directory indexing if nilfs has it.  So even ext3 htree format preserve
both backward/forward compatibility and is well tested code base,
maintaining both htree and btree code is not the best idea.

thanks,
